Marine Propulsion System

The two Royal Danish Navy frigates, Peder Skram and Herluf Trolle have now had considerable time at sea. The authors present results of the Herluf Trolle sea trials and the Peder Skram 500-hr hot section inspection. Problems and developed modifications are discussed. The paper concludes that a marine propulsion system using modified aircraft gas turbines has had sufficient at-sea service so that a designer may specify this application with a high degree of confidence.

Marine Propulsion System

The paper presents the application of artificial neural network for simulation and diagnostic purposes applied to a gas turbine powered marine propulsion plant. A simulation code for the propulsion system, developed by the authors, has been extended to take into account components degradation or malfunctioning with the addition of performance reduction coefficients. The above coefficients become input variables to the analysis method and define the system status at a given operating point. The simulator is used to generate databases needed to perform a variable selection analysis and to tune response surfaces for both direct (simulation) and inverse (diagnostic) purposes. The application of the methodology to the propulsion system of an existing frigate version demonstrate the potential of the approach.

Marine Propulsion System

The Linear Induction Motor (LIM) has been employed as an actuator in conveyers and more recently aircraft launches, and some work has been done on LIMs with a curved secondary reaction plate. This paper presents a working model of a marinised LIM-boat system, with underwater stator operating the hull of a boat which acts as reaction plate. The LIM stator is shown to propel the boat through the water, and that with certain reaction plate metals it will track over the stator coils and therefore be controllable in both direction and speed. Test results for differing coils and reaction plate combinations are provided.
